There is no standard age cutoff for Bone Marrow or Stem Cell Transplants.

An autologous (self-donor) bone marrow/stem cell transplant is practical into the mid-60s, although the upper age limit continues to be expanded into the 70s, depending on the disease, the therapy, and the general health of the patient.

A full myeloablative allogeneic (non-self donor marrow) bone marrow/stem cell transplant is for the most part impractical in patients beyond their mid-50s because of its toxicity, although the upper age limit here is also expanding slightly.

However, a non-myeloablative allogeneic bone marrow/stem cell transplant (sometimes called a "mini-allo") has a different age cutoff. Patients have traditionally undergone these transplants well into their 60's and 70's, depending on the individual, disease, and donor source.
